Sneak into a world of underground assassins as Harman Smith, a man who manifests 7 deadly personalities, the killer7. Take control of this distinct murderers' row as they hunt down the sinister Kun Lan to thwart his plan of world dominance.
The game seamlessly blends on-rails shooting, first-person combat, and light puzzle-solving, creating a unique and engaging gameplay loop. Players take control of Harman Smith and his seven distinct personas, each with their own weapons, abilities, and approaches to tackle various challenges.
One core mechanic is the ability to switch between Harman's seven personas at will. Each personality has unique strengths and weaknesses, requiring players to carefully select the appropriate character for each situation. This adds depth and encourages experimentation with different playstyles to overcome obstacles.
The on-rails shooting segments demand precise aiming and target prioritization. Players must quickly identify and eliminate the invisible "Heaven Smile" enemies, which reveal their weak spots only briefly. This encourages a careful, methodical approach, as players need to scan their surroundings and make split-second decisions on which targets to engage.
In addition to the action-oriented segments, the experience features light puzzle-solving and environmental exploration. Players must navigate levels, uncover secrets, and utilize each character's unique abilities to progress, helping break up the pace of the game.
The game's control scheme, which blends first-person and third-person perspectives, may take some time for players to get accustomed to. However, the developers have implemented a range of control options and accessibility features, allowing players to customize the experience to their preferences.
The ability to switch between the seven personas and the varied approaches they offer encourages players to experiment and explore different strategies. This, combined with the game's branching paths and hidden secrets, provides a high degree of replay value as players discover new ways to tackle the challenges.
